The real image is hidden (I don’t know why ) in Flashing.md and under “Initial serial flashing”
the release: https://github.com/jeelabs/esp-link/releases
The link above is the real image… and flash it with the nodeMCU flasher
If you don’t know the relationship between the nodeMCU and ESP8266 you can refer to my previous article. :https://cmakerhk.wordpress.com/category/hardware/esp/
